| The raw-medicine product caused the mainly contaminating endangers, the component of the pharmaceutical waster water is complicated, contaminate grave. The domestic research and project synthesizing carried out result that many problems and shortages are still exist in the present pharmaceutical waster water treatment technology and handicraft, for its complex and volatile characteristic property. The systematic and all-round studying on the pharmacy waste water treatment technology is requested urgently, in order to satisfying the developing on pharmacy industry.Northeast pharmacy Corp. is priority key enterprise in medicine industry of china, the pharmacy sewage treatment project puts into practice in china firstly, 16 anaerobic and aerobic treatment facilities have been established, a large amount of the operate data and experience was accumulated. Northeast pharmacy Corp. produces synthesizing pharmacy waste water 21000 m3 at present every day, include chemosynthesis and microbe-zymosis pharmacy waste water mainly. The synthetically characteristic is that organic thickness is high, salt amounts are big, the component is complicated, restraint matter is many. Salt amounts and restraint matter, among them, are the most important problem to the micro-treatment technology.The manufacture scale and product variety are increased with the development of enterprise unceasingly. The waste water treatment establishment of Northeast pharmacy Corp. could not satisfy the new circumstances now. That caused the worse waste water treatment effect and running difficult in winter and high running cost. At the same time the exist waste water treatment establishment took the problems of overfull land occupancy and craftwork exhaust gas needed to be resolved. Furthermore the reuse request of treated waste water is more important with the higher cleaning manufacture criterion. Aiming at the Northeast pharmacy Corp. pharmaceutical waster water, a microbial treatment and reuse technology has been designed, on the thesis basis in the study achievement pharmacy waste water handles a technology at home and abroad.The mainly object of research and study is the chemosynthesis and microbe-zymosis pharmacy waste water, with the high organic concentration and high difficulty of degradation. Physical chemistry technology and microbial technology is in common use. Among them, microbial treatment technology gain the more study and the broadest applies, for the property characteristic of low contaminating and high-effect. Assembling the anaerobic and aerobic treatment technology in series, may bring whose respective advantage into play sufficiently, remedy the shortage, and become the main current treatment technology to high organic concentration waste water including pharmacy waste water nowadays. The effective, safe running, convenient operating technology, which can be applied in large scale actual project, become the effort direction in the pharmacy waste water treatment technology field home and abroad.The designed treatment process specifically for Northeast pharmacy Corp. pharmacy waste water and with a view of the enterprise reality is that: pretreatment+ composite hydrolyze acidification + composite aerobic process. Composite hydrolyze acidification, among them, adopt two-stage hydrolyze process. The first stage is the oxygen deficit inner cyclic reactor, with was leads into the biological filling. The second stage is tiny oxygen hydrolyze process, tiny aeration can adjust dissolved oxygen, and can accelerate the water circulating both. Two-stage hydrolyzation acidification reactor may ameliorate the waster water biodegradability noticeably. moreover, the two stages composite aerobic process is formed basis on improved the traditional UNITANK and combined the biological aerated filter. The data of lab-scale test indicated that by the process takeoff rate to raw water COD above 70%. Furthermore under the ideal condition in every process, that the total takeoff rate to raw water COD may reach 82.6% , that proves that to adopt this process to treat pharmacy waste water is feasible and high-effect. The pilot-scale experimental model designed in 10~25 m3/d. The experiment, lasting for 13 months, indicated that the average took off rate of COD in entire process is 84.2%, and may reach 91.1%, in stabilizing period, every process stage can bring the respective treatment function. The pilot-scale experiment carried out that the process is feasible to treat the synthetical pharmacy waste water. The experiment yet studied the most advantaged COD load, and the steady running in winter, and raw water saltness, and the technology to restrain the exhaust gas from hydrolyzation process.At the pharmacy waste water regeneration and reuses aspect, the pretreatment + pair of membrane process was ascertained, with analyzing and choosing, under consider the former pilot-scale test out-flow water quality and Northeast pharmacy Corp. using water quality. The process is mechanical rabble acceleration retention pond + hyperfiltration + reverse osmosis. The pilot-scale test indicated that with the variety of in-flow water quality, the turbidity takeoff rate has been 62.0% ~ 95.2%, and stabilizing under 9 NTU, in pretreatment process, that forcefully guarantee the hyperfiltration and reverse osmosis process. Further the in-flow COD takeoff rate also guarantee 22.3% ~ 44.0%. High quality outflow could be gained from hyperfiltration system set, the out-flow water turbidity stabilizing in 0.13 ~ 0.18 NTU, SDI value is below 2 all the time. That can provided sufficient guarantee for the following reverse osmosis syste.The 240 hours reverse osmosises desalination tests make out that reverse osmosis desalination system runs stability, satisfies desalination rate for 97.6% ~ 98.4%, out-flow water quality satisfy demands.Organic entire scanning is analyzed by the GC/MS to the water sample. The organic containing chlorine, sulfur, phosphorus were found comparatively much in the raw water. Following the course of organic degradation progressing, the chlorine, sulfur, phosphorus get rid of gradually from the organic, become acid radical in water, cause whose contents to increase. And the entire scanning analysis to the raw water and every process out-flow water indicated, that organic in waste water falls off from the 125 kinds for the 11 kinds, general ion flow picture peak height reduces obviously. Explanation most of the organic, can be biodegraded, is already degraded, the residual matter are difficult to be degraded.Microorganism community function diversity analyses a thesis in the handicraft having carried out synthetical pharmacy waste water treatment , the microorganism is playing important role in the process of pharmacy waste water treatment. The microbial diversity of seed sludge and the reactors was also analysed through the use of single carbon source utilization by Biolog ECO plate. The analysis of the microbe metabolization section showed that the adaptability of both seed sludge and the sludge in the hydrolyzation and acidification reactor to the single carbon source environment were slower than that of the sludge in the aeration pool and the biofilm in the biological aeration filter, while the average activity of the microbe had little difference. The diversity index of the carbon source utilization in the ECO plate and the analysis on the principal component analysis showed that these four kinds of the sludge had a resemblance on the richness and evenness of the microbe community, and the popular species of which were not the same, it showed the difference of the structure, species, and the quantity of the microbe community.Four project related technology experiment has been carried out on in the thesis, for the synthesizing pharmacy waste water treatment and reusing project The aeration head experiment studies 29 kinds samples provided by 13 the manufacturer. The eight performance test of aeration head lasted for 6 months. That test data provided the reliable technology basis for project application of the aeration head type choosing. Eight kinds ceramic particle chosen in the homeland manufacturer to test the function respectively. Test indicated that the ceramic particle from 3UW Beijing has the best COD takeoff rate and machinery intensity, Gong Yi Lvyuan is the second. In the thesis from burn and anaerobic digestion and compost and sludge subtraction amount technology four direction, the excess sludge treatment technology were studied. According to characteristic of Northeast pharmacy Corp. pharmacy waste water treatment system, ascertain the chemical abstersion + biological fliteration process used to treat the contaminated gas. Test data display, system runs to the 6th day, deodorization efficiency reaches 99%, the treated gas is lower than the foul smell gas H2S standard that the country stipulates.Basing on the former work, Northeast pharmacy Corp pharmacy waste water biologic treatment project study carried out in June 2003. In August, 2004 the engineering was established, and entered into the debugging. Though already entering winter, the bacteria domesticated successfully, and sludge transforming smoothly inner a month, after sludge inoculation, system has the treatment ability. The close 3 years operation data explanation, system running stably, microorganism system properties are fine , out-flow average COD is 150 ~ 350 mg/L, not only far below the design criterion, but have reached the three-level standard of country city draining off medicine enterprise discharges a standard (COD300mg/L). The waste water regeneration and reuse project was arranged in December, 2006, and has finished the first phase reusing project (800 m~3/d).The comparative analysis by project data of craft brother industry sewage treatment factory it is can be seen, that in the four items economic target is lower than the average value equally. This project land occupied is minor, investment is few, efficiency is high, the handicraft running cost low, etc., and can embodying out the project technology is advanced, economy is rational. Sum up, the thesis bring forward an integrated treatment technology for the Northeast pharmacy Corp. pharmacy waste water, after investigated the raw waste water characteristic, and then carried out the project study. This technology research and the project actualization successfully, treat the waste water contaminant, promoted the water circulation within the enterprise, relieve the water supplying contradiction in Shen Yang City. Furthermore it also provides a technology valuable route for other large-scale pharmacy enterprise environmental protection governs.
